  The following describes the technical solution in the embodiment of the present invention with reference to the accompanying drawings. The following first describes and describes some terms in the embodiments of the present invention.

  A base station, also called a Radio Access Network (RAN) device, is a device that connects a terminal to a wireless network. The base station may be a global base station for mobile communications (Global System for Mobile Communications, GSM®) or a transceiver base station (Base Transceiver Station, BTS) in Code Division Multiple Access (CDMA). Or a Node B (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), or an evolved Node B (Long Term Evolution, LTE) in Long Term Evolution (LTE). Evolved NodeB, eNB or eNodeB), a relay node or access point, a base station in a 5G network, a base station that may appear in another network in the future, and the like. This is not limited herein.

  The terminal may be a wireless terminal or a wired terminal. A wireless terminal may be a device that provides voice and / or other service data connectivity to a user, a handheld device with wireless connectivity, or another processing device connected to a wireless modem. Wireless terminals may communicate with one or more core networks via a RAN. A wireless terminal may be a mobile terminal, such as a mobile phone (also called a "cellular" phone), and a computer having the mobile terminal. For example, a wireless terminal may be a portable, pocket-sized, handheld, computer-integrated, or in-vehicle mobile device that exchanges language and / or data with a wireless access network. For example, a wireless terminal may be a personal communication service (PCS) phone, a cordless phone set, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, or a personal digital assistant. (Personal Digital Assistant, PDA) and the like. The wireless terminal includes a system, a subscriber unit, a subscriber station, a mobile station (MS), a mobile console (mobile), a remote station, and a remote terminal. , Access terminal, user terminal, user agent, or user equipment (User Equipment, UE). This is not limited herein.

  In embodiments of the present invention, “plurality” means two or more than two. The term "and / or" refers to an association relationship to describe a related object and indicates that three relationships may exist. For example, A and / or B may represent the following three cases, namely, the presence of only A, the presence of both A and B, and the presence of only B. The character “/” generally indicates an “or” relationship between related objects.

  FIG. 1 is a framework diagram of a communication system. As shown in FIG. 1, the communication system includes a base station 01 and a terminal 02, and the base station 01 performs wireless communication with the terminal. Terminal 02 supports a first frequency channel number and a second frequency channel number. One of the first frequency channel number and the second frequency channel number may be a primary frequency channel number, and the other is a secondary frequency channel number. This is not limited herein.

  FIG. 2 is a schematic diagram of a CA scenario. CA is introduced in 3GPP, where multiple consecutive or non-contiguous component carriers (Component Carriers, CCs) are aggregated to obtain more bandwidth, thereby meeting 3GPP requirements. As shown in FIG. 2, the terminal accesses a wireless network in cell 1 (Cell 1), and the terminal is a terminal that supports CA, and may report a CA Band combination capability to a base station where Cell 1 is located. . The base station where Cell1 is located may configure Cell2 as a secondary cell for the terminal based on the CA Band combining capability reported by the terminal, such that Cell1 and Cell2 transmit data for the terminal together. The base station where Cell2 is located is a secondary base station. The base station where Cell1 is located and the base station where Cell2 is located may be the same base station or different base stations. Cell1 is a primary cell and corresponds to a primary component carrier (PCC). Cell2 is a secondary cell, and corresponds to a secondary component carrier (Secondary Component Carrier, SCC).

  FIG. 2 shows a CA scenario where two CCs are used as an example. In practice, more CCs may be aggregated to service the terminal.

  For cases in which the operating frequency of a cell belongs to multiple frequency bands, the 3GPP protocol systematically identifies a Multiple Frequency Band Indicator (MFBI) field to identify whether the cell supports multiple frequency bands. Suggest to add to the message.

  FIG. 3 is a schematic diagram of a multiple frequency band scenario. As shown in FIG. 3, Cell1 supports both Band12 and Band17. A terminal supporting Band12 or Band17 can acquire a service in Cell1. For the same physical frequency fc, the frequency channel numbers in Band12 and Band17 are different, and are shown as Earfcn1 and Earfcn2, respectively. One of the two frequency channel numbers is a primary frequency band frequency channel number (primary frequency channel number), and the other is a secondary frequency band frequency channel number (secondary frequency channel number). The primary frequency channel number and the secondary frequency channel number may be identified by a configuration parameter of the frequency channel number. If the parameter is not configured, the base station will assume that the frequency channel number with the lowest frequency band number is the primary frequency channel number and another frequency channel number with the same physical frequency as the physical frequency of the primary frequency band frequency channel number It is assumed to be a secondary frequency channel number.

  After the introduction of MFBI, CA will be affected to some extent. Specifically, when deciding whether to perform carrier aggregation, the base station considers the CA Band combination capability reported by the terminal to the base station and the frequency band of the cell to be aggregated. The CA Band combination capability is used to indicate the Band between which the carrier aggregation supported by the terminal can be performed.

  (1) When the cell to be aggregated supports multiple frequency bands, when the CA Band combination capability reported by the terminal overlaps with the primary or secondary frequency band of the cell to be aggregated , Carrier aggregation may be performed. The CA Band combination capability indicates one or more frequency bands supported by the terminal.

  (2) When the cell to be aggregated does not support multiple frequency bands, carrier aggregation is performed when the CA Band combination capability reported by the terminal overlaps with the frequency band supported by the aggregated cell. Can be done. The CA Band combination capability indicates a frequency band supported by the terminal.

  (3) A service conflict occurs, specifically, the base station has delivered a service instruction of the frequency channel number, and another frequency channel number having the same physical frequency as the physical frequency of the frequency channel number, When the expected target frequency channel numbers for carrier aggregation are, carrier aggregation cannot use these frequency channel numbers.

  In view of this, in one embodiment of the present invention, a service instruction method is provided to solve the service contention problem. The solution in this embodiment of the present invention can solve the service contention problem by multiplexing frequency channel numbers.

  A3 event: The signal quality of the neighbor cell of the primary cell is higher than the signal quality of the primary cell by a specific threshold.

  A4 event: The signal quality of the neighbor cell of the primary cell is higher than the corresponding threshold.

  A5 event: The signal quality of the primary cell is lower than threshold 1, and the signal quality of the neighboring cells of the primary cell is higher than threshold 2.

  A6 event: The signal quality of the intra-frequency neighbor cell of the secondary cell is higher than the signal quality of the secondary cell by a specific threshold. The base station may change the secondary cell without changing the primary cell through the A6 event.

  A periodic measurement may be a measurement that does not have an evaluation condition such as a threshold and is not triggered by an event, but may be a measurement in which information is reported to a base station at periodic intervals when information may be obtained. Periodic measurements may include strongest cell measurements, cell global identification (CGI) measurements, and so on.

  Event or periodic measurements may be triggered by a corresponding preset algorithm. The preset algorithm may include a measurement report (MR) algorithm, a handover algorithm, an automatic neighbor relation (ANR) algorithm, and the like.

  S403. The base station sends second service indication information to the terminal, where the second service indication information includes an identifier of the first frequency channel number and an identifier of the second service.

  Specifically, after transmitting the first service instruction information including the identifier of the first frequency channel number and the identifier of the first service to the terminal, and of the second service associated with the second frequency channel number When it is necessary to send a service indication to the terminal, the base station notices that the physical frequency of the second frequency channel number is the same as the physical frequency of the first frequency channel number, and the identifier of the second frequency channel number. Cannot be added to the service instructions. In this case, in the solution of this embodiment of the invention, the identifier of the first frequency channel number is multiplexed to indicate the second service to the terminal.

Specifically, after the identifier of the first frequency channel number is conveyed in the second service indication information and, as a result, the service identifier associated with the frequency channel number is indicated, the service identifier is different from that of the same physical frequency. May be further indicated for the service associated with that frequency channel number to avoid service contention caused by the same physical frequency.
